When a patient has a heart attack, the doctor has to make a choice: either treat the patient with clot-busting drugs or perform invasive surgery. But how do doctors decide which procedure is best, and how do those decisions affect patient outcomes? Princeton professor Janet Currie decided to investigate these questions. She discusses the findings on this episode of WooCast, the Wilson School's podcast series.

The measles virus can cause serious disease in children by temporarily suppressing their immune systems. This vulnerability was previously thought to last a month or two; however, a new study shows that children may in fact live in the immunological shadow of measles for up to three years, leaving them highly susceptible to a host of other deadly diseases.

Princeton University-led research provides a new weapon in the struggle against the devastating wildlife trade: the very markets where animals are bought and sold. The researchers found that species that are disappearing as a result of the pet trade can be identified by changes in their market prices and trade volumes — increasing prices and decreasing availability could mean that wild populations are plummeting. Regular pet-market monitoring could help indicate when a particular species is in trouble so that measures could be taken to monitor and protect its wild population.

Princeton University researchers "weighed" Antarctica's ice sheet using gravitational satellite data and found that during the past decade, Antarctica's massive ice sheet lost twice the amount of ice in its western portion compared with what it accumulated in the east. Their conclusion — the southern continent's ice cap is melting ever faster.

The discovery of a single anatomical difference between males and females of a species of Stegosaurus provides some of the most conclusive evidence that some dinosaurs looked different based on sex, according to new Princeton University research.

When it comes to the brain, "more is better" seems like an obvious assumption. But in the case of synapses, which are the connections between brain cells, too many or too few can both disrupt brain function.

Princeton University researchers offer a new theory that an early-life injury to the cerebellum disrupts the brain's processing of external and internal information and leads to "developmental diaschisis," wherein a loss of function in one brain region leads to problems in another. Applied to autism, cerebellar injury could hinder how other areas of the brain interpret external stimuli and organize internal processes.

Despite years of research, the genetic factors behind many human diseases and characteristics remain unknown, and has been called the "missing heritability" problem. A new study by Princeton University researchers, however, suggests that heritability in humans may be hidden due only to the limitations of modern research tools, but could be discovered if scientists know where (and how) to look.

Princeton University researchers report in the journal Science that collective intelligence is vital to certain animals' ability to evaluate and respond to their environment. The results should prompt a close examination of how endangered group or herd animals are preserved and managed because wild animals that depend on collective intelligence for migration, breeding and locating essential resources could be imperiled by any activity that diminishes or divides the group, such as overhunting and habitat loss.

Princeton University researchers developed a mathematical framework that strips away the differences between scientific laws and theories to reveal how the ideas are compatible.
